  • The current evaluation time period for the construction management service is the project completion or after project completion. Therefore, the construction manager has the following problems. First, it is difficult to prepare the evaluation due to the new field movement of the existing participating engineer. Next, the CM work is complex as well as extensive. Therefore, the critical success factors of the construction technology services evaluation are required as a systematic performance standard of CM work. In this study, we extracted the critical success factors that can systematically prepare the evaluation from the early stage of the project through in - depth interviews with experts. And, this study was analyze the priority of each factor by using AHP technique. As a result, the most important factors were related to the systemization of the preparation process, the construction manager work capabilities and practical construction management. And the priorities of all factors were analyzed high in the factors suggested by the owner groups. The results of this analysis are expected to provide the standards that construction management service performer carry out structured management of construction management throughout the project.

  • The school complex project is driven by public calling for school facilities change due to the social change followed by the aging society and increasing interest in the lifelong education. The school complex project is defined as an activity in which the school facilities and space are not only used for students, but also for the local residents. Since the project was promoted in a link with reform of the education system in 2001, the demand in the expectation effect has been sharply increasing. Despite of the high expectation and attention, the school complex project, however, has been performed in a limit of efficiency. Consequently, public opinion calling for more structured and effective way on construction and administration has been certainly increasing. According to the strong demand, this study was carried out to provide basic data for, and suggest an approach to, more structured and effective way of establishment and administration of the school complex project by comparing the success cases in Seoul metropolitan city.

  • Indian Construction industry is large, volatile, and requires tremendous capital outlays. Typically, the work offers low rates of return in relation to the amount of risk involved. A unique element of risk in the industry is the manner in which disputes and claims are woven through the fibre of the construction process. Delay is generally acknowledged as the most common, costly, complex and risky problem encountered in construction projects. Because of the overriding importance of time for both the Owner and the Contractor, it is the source of frequent disputes and claims leading to lawsuits. The growing rate of delays is adversely affecting the timely delivery of construction projects. Presently construction industries are facing a lot of problems, considering that a paper assess construction stakeholder's perception to the causes of delays and its effects on project delivery. And also one case study is considered in this paper to elicit responses from construction stakeholders. The primary aim of this paper is to identify the perceptions of the different parties regarding causes of delays, the allocation of responsibilities and the types of delays, and method of minimizing the construction delays.

  • 최근 공사규모의 대형화, 복잡화 등으로 토목, 건축, 기계 등의 복합공종으로 구성된 공사들은 공기절감을 위해 패스트트랙(Fast Track) 방식으로 진행되는 사례가 많으며, 패스트트랙 방식에서는 적정 단계구분이 전체 프로젝트의 공기 책정에 중요한 사안이다. 본 연구에서는 복합공종으로 구성된 건설공사가 패스트트랙으로 진행될 때 적용할 수 있는 단계구분 방식을 제시하고 있다. 이를 위해 연구에서는 토목, 건축공사로 구성된 4개의 축구전용경기장 공사를 적용 사례로 분석하여 세분화된 공정분류체계(Work Breakdown Structure, WBS)를 통해 주요 단계별 공정 구분에 의한 일정표를 분석하고, 5가지 시안을 적용하여 패스트트랙 단계구분의 적정성을 분석한다. 분석된 시안중에서 최소 공기를 갖는 시안에 대하여 패스트트랙 단계구분 및 단계별 주요 공정의 구성 모형을 제시하였다. 이러한 방법론은 패스트트랙이 적용되는 유사한 규모의 대형 복합공사에서 패스트트랙 적용 시에 적정 단계 구분과 단계별 공정 구성 체계에 활용성을 가질 수 있다.

  • This study uses a hybrid estimation tool for effective cost data management of building projects, and develops a realistic cost estimation model. The method makes use of newly available information as the project progresses, and project cost and percentage progress are analyzed and used as inputs for the developed system. For model development, case-based reasoning (CBR) is proposed, as it enables complex nonlinear mapping. This study also investigates analytic hierarchy process (AHP) for weight generation and applies them to a real project case. Real case studies are used to demonstrate and validate the benefits of the proposed approach. By using this method, an evaluation of actual project performance can be developed that appropriately considers the natural variability of construction costs.

  • In a super-highrise residence project, a project manager needs to form the long-term risk management plan which covers the problems from the beginning of project to the time of demolition. The cause and responsibility for a risk are clarified and quantitatively evaluated through the life cycle of a project. Development of the system which supports a risk strategy effectively is needed as a project becomes complex. In this paper, through the life cycle of a specific super-highrise residence project, a risk phenomenon is specified from a viewpoint of each participant, and the mathematical model is formulated choosing the combination of the optimal strategy against a risk quantitatively within a fixed risk strategy budget.

  • In the Urban Regeneration Project, the scale becomes huge and the composition of participating organizations is complex. It is necessary to establish the master plan fast and effectively harmonize conflict options and interests in the early stage of the project. However, the master planner, who is tasked to establish the master plan, and the master planning team, are difficult to establish the master plan fast while effectively considering various and complex information related to regeneration. The Urban Regeneration Project is composed of various types of computer files like HWP, EXL, PDF, DWG and others. When the master plan is established, it is necessary to link the information items and physical files of urban generation in order to effectively save the files in storage for easy search and utilization. This study developed a prototype system to support participating subjects of the Urban Regeneration Projects. It will effectively utilize the information items in the physical computer files using information blocks and Metadata. The developed system provides the base to effectively manage large amount of documents in the early stage of the Urban Regeneration Project and make effective decision-making using the concept of data warehouse.

  • 최근 도시 미관이 중요시 되면서 동일 아파트 건설단지 내에서 저층과 고층 아파트가 혼합배치되는 경우가 많아지고 있다. A공사에서 발주한 아파트 사업지구 중 고층 동들과 저층 동들 간의 층수 차가 4층 이상인 지구가 약 33%인 것으로 조사되었다. 일반적으로 아파트 공사의 공기는 단지 내최고층 동을 기준으로 산정한다. 이로 인해 전체 사업지구의 공사기간이 길어지고, 길어진 공기는 해당사업의 사업성에 나쁜 영향을 미친다. 그러므로 동일 단지 내 저층 고층 아파트 동들이 혼합 배치된 사업지구(이하 "혼합사업지구"라 한다)의 사업성 제고를 위해 일부 고층동 아파트의 골조공기를 단축해야 할 것이다. 그러나 혼합사업지구의 다양한 유형으로 인해 어떤 경우에는 공기단축이 사업성을 더 나쁘게 만들 수 있다. 따라서 본 연구에서는 다양한 유형을 갖고 있는 혼합사업지구의 골조공기 단축 여부를 판단할 수 있는 자료제공을 위해 혼합사업지구의 일부 고층동에 대한 골조공기 단축이 건설사업비에 미치는 영향을 분석하여 그 결과를 제시하였다.

  • According to the construction plan of Samcheok electric power complex from year 2009 to year 2020, many people are interested in this area. This national project which invests about 8.6 trillion won will have great influence to rail transport considering current depression days. Samcheok electric power complex will be the largest plan in Korea, and it is necessary to have railroad construction plan as soon as possible considering the route change of domestic coal transport and the possibility of coal transport by rail from North Korea, Russia and China after reunification of Korean peninsula. Also, Samcheok electric power complex will be located in the east area railroad route and it is important to study about this area. This study will mention about the railroad route of east sea north line and Pohang $\sim$ Samcheok line, and review the prospect and strengthening method of coal transport by railroad according to the construction of Samcheok electric power complex.
